What is the value of x? enter your answer in the box. x =

it is an eqilateral triangle, 3 equal sides 3 equal angles (60°)

so

2x - 4 = 60

2x = 60 + 4

2x = 64

x = 64 : 2

x = 32 (your answer)

2 * 32 - 4 = 60

the answer is good.

if you want the value of y

60 : 5 = 12

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
